Introduction: Orthodontics a unique branch in dentistry is inter-related with biology, mathematics and engineering sciences. Biomechanics is fundamental to the practice of orthodontics. Stresses generated at any point during orthodontic treatment are critical in remodeling of bone and type of tooth movement. Aims and Objectives: The aim of the following study is to determine the initial stresses produced in the tooth, periodontal ligament (PDL) and bone when force is applied on the tooth for intrusion and tipping on labial and lingual sides in the presence of varying alveolar bone heights. Materials and Methods: A geometric model generated using AutoCAD (Autodesk, Inc.). Six three-dimensional finite element models of a maxillary central incisor were designed with PDL and varying alveolar bone heights after applying the boundary conditions of the model, force was applied on the tooth. Results: Results were obtained with color coded three-dimensional fringe patterns. Conclusion: Alveolar bone loss causes an increase in the maximum initial stresses relative to the bone heights.
